摘要
磬是我国一种非常古老的打击乐器,其产生距今至少已有4000多年的历史。《考工记》最早记述了磬的形状、规范和调音技术。磬的重心和磬的悬孔位置的确定是制造磬体的重要环节,直到明清之际,西方力学知识传入中国并逐渐被中国学者接受,磬体(倨句型)重心位置的问题才引起研究《考工记》的学者的关注,他们开始利用数学方法研究磬体的重心位置问题。清代学者程瑶田、汪莱在这方面进行了开创性的研究,但未能获得完全正确的解法。此后邹伯奇不仅指出了程、汪二人工作的不足与错误,还获得了正确的求解方法与结果,使磬体重心问题获得圆满的解决。
With a history of more than 4,000 years, Chime Stone is a very ancient percussion instrument in China. Kao Gong Ji （Artificers＇ Record） was the first book to describe its shape, standard and tuning techniques. Locating the center of gravity and hanging hole on chime stone was crucial for the manufacturing work. In ancient times, however, the ways to find its center of gravity had not been defined for a long time until the Qing Dynasty when Chinese scholars gradually accepted the western concept and knowledge of center of gravity. Among them, scholars who studied Kao Gong Ji began to focus on Chime Stone＇s center of gravity and locate it by use of mathematical methods. Then Cheng Yaotian and Wang Lai conducted a groundbreaking research, but resulted in an incorrect solution. Finally, Zou Boqi found out the key problems in the study by Cheng and Wang and got ac- curate results in locating the center of gravity for Chime Stone.
